Although cable can be appealing because of its price, there
are some inherent drawbacks to cable modem service. First, the cable network is shared,
which means as the number of cable users increases the speed on each individual's line
decreases. Second, a shared network is inherently less secure than a dedicated service
like DSL, as neighboring cable customers can more easily intercept data or hack into
another user's computer. Third, the upstream speed on a cable modem is generally no higher
than 128 Kbps. Thus, cable modems are unable to provide acceptable levels of speed or
security for business purposes.
